Is there anywhere I can buy just a J-link Lite? We have a couple of developers working on the nRF51822 and I need to get some additional debuggers, and would rather not buy another development kit, just for the debugger. I've looked on Segger's site, and I can find the lite but there is not purchasing information.
Second question, is it worth getting on of Segger's more advanced debuggers? Which one would you recommend - I'm using Keil uVision 5, so it needs to work with Keil.
